Abstract

In this study, the development of European Sea Bass (Dicentrarchus labrax L., 1758) eggs was investigated at different temperatures. The experiments were carried out at 15 degreesC and 17 degreesC. The average diameters of the eggs were determined robe approximately 1.162 +/-0.004 mm. The embryonic development of the eggs was observed every hour and then photographed. The hatching rates were found to be 84.8-89.4% at 15 degreesC and 82.3-86.3% at 17 degreesC, respectively. Hatching of the larvae took 87 hours at 15 degreesC and 69 hours at 17 degreesC.
